Description

Cassette tape and apparatus for playing the same

The present invention relates to a cassette tape and a reproducing apparatus, and more particularly, a cassette tape which records audio, text and game data on a four-track magnetic tape so that audio, text and games can be reproduced by a user's selection. The playback apparatus is related.

In general, a cassette tape recorder (hereinafter referred to as a cassette player) is an audio-only device for recording an audio signal on a tape or reproducing an audio signal recorded on a tape.

Therefore, when the user listens to music using the cassette player, there is no problem. However, when the user studies a foreign language using the cassette player, there is an inconvenience in that the user must view the learning aid separately while listening to the playback signal of the cassette player.

Recently, a cassette player with a caption function has been developed, and when a foreign language is studied, only the cassette tape is played, and characters are displayed along with an audio signal, which helps a lot of foreign language studies.

Referring to the process of recording and reproducing the audio signal and the character information signal of the tape used in the cassette player having the caption function, as shown in FIGS. 1A and 1B, the tracks A and B of the cassette tape are shown. Record the character information signal corresponding to the audio signal ahead of a predetermined distance before recording the audio signal to the audio signal, or when recording the audio signal of track C, the character information signal corresponding to the audio signal is almost at the recording position of the audio signal. The same will be written.

Therefore, as shown in Fig. 1B, the audio signals of the tracks A and B are recorded before the audio signals of the tracks A and B are recorded in the cassette tape playback in which the audio signal and the character information signal are recorded. In the case where the character information signals corresponding to the audio signal are first recorded, the character information signals of the track A and the track B are reproduced first, and then the audio signals of the track A and the track B are reproduced, and then the audio signals of the track A and the track B. Is reproduced and output to the speaker, whereby the audio signal and the text information signal can be displayed.

In addition, if the character information signal corresponding to the track C is recorded at the beginning of recording the audio signal of the track C, the audio signal of the track C is reproduced while the character information signal of the track C is reproduced. After a predetermined time after the signal is output to the speaker, the character information signal of the track C can be displayed.

As described above, the cassette player and the cassette tape having the caption function help to learn a foreign language. However, when playing a game using the cassette player, there is no function for executing data and games for the game. Since it is not possible to use the game machine, if you want to play the game has had an uneconomical problem to purchase a separate game machine.

Accordingly, an object of the present invention is to record audio, text, and game data on a track of a cassette tape, and to play audio, text, or game data according to a user's selection. It is to provide a playback device.

In addition, the buffer and memory unit 101 is constituted by a read / write memory device that reads and temporarily stores analog signal data recorded on a four-track cassette tape 10.

Effects of the cassette recorder for game and character display of the present invention configured as described above are as follows.

First, the left and right audio signals are recorded on the track 1 and the track 2, respectively, the character signals are recorded in the analog form in the track 3, and the track 4 is the 4 track cassette tape 10 in which the game data is recorded in the analog form. When the desired key is selected through the keypad 102, the microprocessor 100 controls the preset program, and outputs the controlled signal to the deck controller 50. The deck control unit 50 causes the cassette deck unit 40 and the magnetic head 20 to perform a reproducing operation with a control signal corresponding to the signal selected by the user.

At this time, the magnetic head 20 reads out audio signals recorded in tracks 1 and 2 of the 4 track cassette tape 10, text and command signals recorded in tracks 3 and 4, and game data.

The audio signals, texts, command signals, and game data thus read are amplified and output to a predetermined level through the preamps 30-1, 30-2, 30-3, and 30-4.

Among the signals amplified and output to the predetermined level, the audio signal is mixed with a predetermined sound effect through the sound mixer 60, which is provided through the microprocessor 100 to be described later.

Next, the audio signal mixed through the sound mixer 60 is amplified to an audible frequency region through the stereo speaker amplifier 90 and then output through the speaker 104.

On the other hand, the character and command signals and game data amplified and output through the preamps 30-3 and 30-4 are digital signals through the first and second A / D converters 70 and 80, respectively. The digital signal is converted into and input to the microprocessor 100, and the input digital signal is stored in the buffer and the data storage unit 101 by the control signal of the microprocessor 100.

In this case, the signal stored in the buffer and the data storage unit 101 is 4 bytes of data including 2 bytes of character information and 2 bytes of position information, which is read first of the 4 bytes of characters read through the cassette tape 10. The on 2-byte code is a font data conversion code stored in the internal memory of the microprocessor 100, and this code functions to transfer the corresponding character to the LCD panel 103.

The two bytes read later have the position information of the character to be displayed, and determine the horizontal position and the vertical position of the LCD panel 103 for the 256 gray levels.

Therefore, the digital data stored in the buffer and the data magnetic field 101 are displayed on the LCD panel 103 under the control of the microprocessor 100. Here, the LCD panel 103 uses an LCD panel device of a graphic control method that can freely express characters or pictures.

Therefore, when the user wants to play a game, the microprocessor 100 is mounted on the deck on the four-track cassette tape 10 on which audio, text, and game data are recorded, and then the game is selected through the keypad 102. The four track cassette tapes 10 are read through the magnetic head 20, and the read audio signals are amplified through the respective preamps 30-1 and 30-2, respectively. A) mixed with the sound effect input to the microprocessor 100 through a) and amplified through the stereo speaker amplifier 90 is output through the speaker 104 so that the user can hear.

Meanwhile, the character and game data signals read through the magnetic head 20 are amplified by the preamps 30-3 and 30-4, respectively, and the amplified character and game data are first and second A / D. The digital signal is converted into a digital signal through the converters 70 and 80 and input to the microprocessor 100.

Therefore, the microprocessor 100 controls the input digital signal to display the characters and games while controlling the LCD panel 103, thereby allowing the user to display the characters and games displayed on the LCD panel 103 and the speaker. You can enjoy the game while listening to the sound effect (104).

As described above, according to the cassette tape and the playback apparatus of the present invention, a picture, letters, numbers, and sounds are simultaneously recorded on a magnetic tape without a separate computer main unit and a monitor (CRT) for displaying character information and game information. The learning effect is excellent because there is an advantage of storing and repeating it according to the taste of the user.

In addition, the present invention has the advantage that the audible signal in stereo and the viewing signal is displayed on the LCD panel when playing the data recorded on the magnetic tape to enjoy the existing cassette tape player and game functions at the same time.

In addition, since the present invention records predetermined information on each of four tracks of the magnetic tape, by recording / reproducing a large amount of data at a time, it is possible to compensate for the disadvantages of the existing magnetic tape recording medium and to reduce manufacturing costs.
